The Boron plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Boron’s center stands about 2,470 ft above sea level. Within three miles the land runs from 2,390 ft to 2,730 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Red Buttes, about 3,400 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 18 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Mafic-volcanic, greenstone. Age: Paleozoic to Mesozoic, 66 to 542 million years old. About 0.6 mi of the line.
Rhyolite, basalt. Age: Early Miocene to Early Pliocene, 4 to 22 million years old. About 0.3 mi of the line.

Rain that falls on Boron runs only a short way, about 4 miles, to Rogers Dry Lake. Rogers Dry Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
